To all whom it may concern: 1

Be it known that I, JOHN H. STEINMETZ, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and use ful Improvements in Adjustable Stools, ofwhich the following is a specification.

This invention relates broadly to stools in general but has moreparticular reference to stools of the type generally known as musicstools or piano stools and aims to provide a stool of this characterwith an adjustable seat which may be tilted. or inclined to suit theconvenience of the user. i p

For certain classes of musical instruments, for example, pianos, inwhich the finger keys are used, a piano stool. having a horizontal seatis preferable and almost universally employed. For certain classes ofmusical instruments, particularly the mechanical class, such as pianoplayers and, also, for certain classes of musical; instruments requiringconsiderable force to operate the pedals, such as pipe organs, it isessential that the stool or bench be inclined toward the instrument soas to throw the weight of the player into the action of the feet. Inorder to avoid the expense and inconvenience of having two seats of thischaracter for the different uses to which they maybe put inthe samehousehold or music room, it has been. proposed to make the seats ofpiano stools and benches position. I

My invention relates partlcularly to a stool or bench of this lattertype and has for its object to provide an improved means of adjustmentwhereby the stool or bench is adapted to be used with. the seat ineither the horizontalor inclined position and which is adapted to bereadily converted or ad- The primary objects of the invention are toprovide a stool, the seat of which is adjustable, so that it may be usedin a horizontal position or in an inclined position and which will bestrong, durable and practicable and which will be cheap to manufactureand easy to assemble.

to an inclined These desirable ends I Other objects and advantageswill-be apparent as the inventionvbecomes better understood by referenceto the following description when considered in connection with the.accompanyingdrawings. a

1 Referring "to the j drawings Figure 1 is an elevation of a stoolembodying my inventionjFig. 2 is an -enlarged fragmentary view of theadjustable seat support; and Fig. 3 is aflongitudinal sectional viewtaken substantially onthe line 3- -3 of Fig. 2.

On the drawings reference character 5 designates generally the base ofthe stool which may be of any preferred shape or construction, thecenter piece 6 ofwhich is" interior-1y threaded to receive a threadedsupporting post 7. This construction-is customary in piano stools andother stools of seat at any height conveni'entto thenuser.

Inthepresent instance the post 7 is flattened on opposite sides abovethe threaded portion, as indicated by reference character 8, and isequipped with laterally projecting studs 9 and 10, respectively, ,whichextend outwardly from the flat faces 8. The seat 11, which may be ofanywell known or preferred construction, has attached to its posedadjacent its lower end to receive the ends ofthe stud 10 and, also, withan irregular shaped aperture 15 above the slots.

1 1 to-receive the ends of the stud 9. The aperture 15, as best shown inFig. 2, is sub-. stantially circular in contour with a bossl6 dependingfrom its top. This boss is provided at its lower end with a depressionforming a bearing recess 17 and the tops of the apertures on eachsideo'f the boss 16 provide bearing recesses 18, each of the recesses1'] and 18 being adapted to form a bearing support upon which the'seat11 is supported from the stud 9. The ends of the studs 9 and 10 areriveted over and,.if desired, washers 19 may beemployed to in suremaintenance of the lugs 13 in proper relation with the supporting post.

When the bearing recessll and the boss 16 are engaged with the stud 9the seat is maintained in horizontal position as shown in Fig. 2 and infull lines in Fig. l. The stool may then be used as an ordinary pivotstool and may be adjusted to the requisite height by revolving it on thestationary base in the usual manner. When the user desires a stool withan inclined seat the inclination may be readily effected by simplyraising;the's'eat to disengage the bearing recess .17 from the stud 9and then tilting the seat in one direction or'the other about the stud10 as a pivot, thereby engaging the stud 9 in the aperture 15 at oneside of the boss 16 so thatwhen the seat is released the stud 9 will beengaged in one of the bearing recesses 18 at the top of the aperture 15and the seat'will be inclined, as shown in dotted seat against tiltingmovement about the stud 9 as a pivot. While I have shown a pair of lugsor members 13 attached to the seat, it will be obvious that thesemembers might, if preferred, be'made in one piece constructed to receivethe upper end of the supporting post and, through the instrumentality ofthe slot, aperture and studs, afford an adjustable connection betweenthe post and the seat.

It will be manifest from the foregoing,

that I have provided a stool the seat of which may be readily convertedfrom a hori- :AOIltLl to an inclined position by simply liftlng the seatand tilting it to the required position, that the seat will alwaysmaintain Oopieaof this patent may be obtained for the position to whichit has been adjusted and, that the stool may be used with the seat inhorizontal position as an ordinary piano stool, if'preferred, theadjustment from one position to the other being readily accomplished, aspreviously described.

While I have shown and described a preferred embodiment of my inventionit will be obvious that various changes in the construction, proportionand arrangement of the various parts may be resorted to withoutdeparture from the essence of the invention as set forth in thefollowing claim.

I claim:

An adjustable stool, comprising a base, a post vertically adjustablethereon, a pair of pins extending laterally from each side of the post,a seat, a pair of members secured to said seat and extending downwardlytherefrom on each side of said post, each member being provided near itslower ends with a longitudinally extending slot engaged with the lowerpin on said post to provide a sliding and pivotal connection betweensaid post and said member, each member being provided above said slotwith an arcuate slot engaged with the upper pin of said post and acentral boss having a depression, said dcpression in the ends of saidslot forming a central and two lateral seats for the reception of saidupper pin and by means of which said seat is adjustably supported uponsaid upper pin.
